Answer. -
2) Question.

Answer.In compression 12 t
-
3) Question.

Answer.
-
4) Question.
For field rivets, the permissible stresses are reduced by what percentage?
Answer. -
5) Question.
Steel structures are ideally suitable for impact loads because they have high
Answer. -
6) Question.
What is the ratio of the yeild stress in power driven shop rivets relative to the permissible bearing stress of mild steel?
Answer.The question is from WSM as rivet is mentionedNow, design stress in axial tension = 0.6fy and design bearing stress = 0.75fy
Now, for bolts/rivet, fy is not defined So we take fu which is approx 400 Hence yield stress for for rivet = 0.6 * 400 = 240
In bearing stress = 0.75fy
Hence, 0.6/0.75 = 0.8 -
7) Question.
In a riveted joint, failure will occure due to which one of the following?
Answer. -
8) Question.
A plate used for connecting two or more structural members inserting each other is termed as
Answer.A plate used for connecting two or more structural members intersecting each other is termed a Gusset Plate.
A gusset plate is a thick steel sheet used to join multiple structural members together, often seen in truss structures or where beams and columns intersect. -
9) Question.
Which of the following does not describe a weld type?
Answer. -
10) Question.
The type of stress include in the foundation bolts fixing a column to its footing is
Answer.When a column is fixed to a footing, the bolts are designed to resist the upward pulling forces (tensile forces) that could cause the column to lift off the foundation. This is known as pure tension.
